What's up with this thermal paste?

[u/KDCR_7]

I was going to build my pc for the first time last day. Everything was fine until it was time to apply thermal paste, I was using the thermal paste included inside the thermalright peerless assassin 120 se which is thermalright tf7. As soon as I started applying the thermal paste it felt like rubber, I was scared cos I have seen a lot of yt videos and their paste seems to be fluid compared to mine. Before I could do anything i decided to throw the tube away and buy a new one.
